The ever-growing number of states which have legalized either medical marijuana or recreational marijuana has created a number of issues for law enforcement and the justice system. Chief among those issues is the challenge of enforcing laws against operating a vehicle under the influence of marijuana. In an effort to overcome this challenge, the Norwegian company Drauger developed the DrugTest 5000. This system uses a mouth swab, taken roadside, to help determine if a driver is under the influence of marijuana or other drugs. The DrugTest 5000 has been in use in Norway since 2015 and has seen growing use in the United States. This test, however, is probably not the solution for law enforcement’s problems.
